The image depicts a simple pendulum with two bobs, one at rest and the other swinging. The image is a line drawing and depicts a simple physics concept of a pendulum, with two circular bobs, one labelled A and the other B, connected to a horizontal line by a string. Bob B is swinging in a clockwise direction and Bob A is at rest. The image is simple and straightforward, devoid of any emotion or mood.

The correct response is:
Total mechanical energy stays the same.
In the absence of friction or other dissipative forces, the total mechanical energy of the pendulum (the sum of its potential energy and kinetic energy) remains constant as it swings from point A to point B. This is a consequence of the conservation of mechanical energy.
